（本经下品）
帅气卫外，左右二十有四，而营队居中，设无血帅，谁主司命乎。
【气味】苦寒，无毒。
【主治】主鬼疰贼风蛊毒，杀精物恶鬼，腹中毒邪气，女子赤沃漏下。
【核】曰∶出代郡，及姑幕。北山经云∶少阳之山，中多美赭。西山经云∶石脆之山，
灌水出焉，中有流赭。管子云∶其山有赭，其下有铁。处处山中亦有之，西北者为良也。生
山峡中者，赤红青色而有泽，上纹如浮沤，俗呼丁头赭。修事，细研，以腊水重重飞过，水
上有赤色如薄云者去之。澄净去水，再以茗汁煮一伏时，取出，研万余匝用。铁铛烧赤，下
白蜡一两，待化，投新汲水冲之，再煮一二十沸，取出，晒干用。
先人云∶去浮赤，夺其先声；烹白蜡，培其根本；肝与血，大获保任矣。
【 】曰∶灵枢称卫气为帅气。隐居称大赭为血师，则大赭当为营气之司命矣。经云∶
命曰营气，以奉生身，莫贵乎此。先人云∶鬼疰三证，大为生气之害，然必伏匿阴血中，乃
肆毒恶。赭色丹青，承宣君相火，为血帅保任，仍令就规矩，会尺寸，以合五十营，奉身生
气如尝，营血安堵如故矣。
（本经下品）
【气味】咸寒，无毒。
【主治】主明目，目痛，益气，坚筋骨，去毒蛊。
【核】曰∶戎盐，即青盐，亦赤盐也。史书言虏中盐有九种∶曰白盐、食盐、黑盐、胡
盐、柔盐、赤盐、驳盐、臭盐、马齿盐，而戎盐即胡盐。日华一名羌盐，《唐本》一名秃登
盐，大明一名阴土盐，生河崖山 之阴土石间也，大小不尝，形作块片，间有方棱，或如鸡
卵，或如菱米，坚结似石，色玄紫白，味不甚咸，臭若 鸡之气，烧之不鸣 者是也。凉州
异物志云∶姜赖之墟，今称龙城。刚卤千里，蒺藜之形。其下有盐，累棋而生。又云∶盐山
二岳，二色为质，赤者如丹，黑者如漆。小大从意，镂之为物。作兽辟恶，佩之为吉。或称
戎盐，可以疗疾。张果《玉洞要诀》云∶赤戎盐，生西戎，禀自然水土之气，结而成质。其
地水土之气黄赤，故盐
时，色益赤者为真。再烧之最久，赤转为青矣。故一名绛盐。西凉记云∶有青盐池，出青盐，
正方寸半，其形如石，味甚甘美。真腊记云∶山间有石，味胜于盐，可琢为器。梁杰公传云∶
交河之间，掘碛下数尺有紫盐，如红如紫，色鲜而甘。其下丈许，必有 珀。北户录云∶张
掖池中生桃花盐，色如桃花，随月盈缩。今宁夏近凉州地，盐井所出青盐，四方皎洁如石。
山丹卫，即张掖地，有池产盐红色。此二盐者，即戎盐之青、赤二盐也。今方书但用青盐，
不用赤盐，并目赤盐为异物矣。本草云∶北海产青盐，南海产赤盐，总从西戎来。所谓南北
者，指西海之南北耳。岭南一种红盐，用色染成，非真赤盐也，烧之出白汁，凝定仍转白色
矣。丹房 源云∶蛮盐可伏雌雄，唯赤盐为上。独孤滔云∶戎盐累卵，干 ，制土砂。
【 】曰∶煮海为盐，若戎盐者，钟海水自然之精气，不假人力为也。生海北者黑如漆，
海
不越水火为色，递以水火为胜劣，亦递以水火为功用也。故主精明眼识为缘，生于眼识，盖
识精缘水为根，缘明为尘，尘为火用，根为火体故尔。若益气坚筋骨，去毒蛊，此宝明澄湛
之休征耳。
（宝明即火，澄湛即水。经云∶宝明生润，水从火出矣。）
【本经下品】
帅领卫气护卫体表，左右各有二十四位（指手足三阳经之卫气分布），而营气队伍居于中央。如果没有血之统帅，谁来主宰生命呢？
【气味】味苦，性寒，无毒。
【主治】主治鬼疰、贼风、蛊毒，能杀死精怪恶鬼，清除腹中的中毒邪气，治疗女子赤白带下及漏下不止。
【考证】曰：代赭石产于代郡以及姑幕。《北山经》说：“少阳之山，山中多产美赭。”《西山经》说：“石脆之山，灌水发源于此，山中有流赭。”《管子》说：“那山有赭石，山下有铁矿。”各处山中都有出产，以西北地区的为优良。生长在山峡中的，呈赤红青色且有光泽，表面纹理像浮沤（水泡），俗称丁头赭。炮制方法：细研后，用腊月水反复漂洗，将水面漂浮的如薄云般的赤色杂质去除。澄清去水后，再用茶汁煮一个时辰（约两小时），取出，研磨上万次使用。或用铁锅烧红，放入一两白蜡，待其熔化，投入新汲井水冲激，再煮沸一二十次，取出晒干使用。
前人曾说：去除浮赤之色，是剥夺其先声（即去除其燥烈之性）；烹煮白蜡，是为了培补其根本；这样对肝与血的保全和任护就大有裨益了。
【按语】曰：《灵枢》称卫气为“帅气”。陶隐居称大赭石为“血师”，那么大赭石应当是营气的统帅。经文说：“命名为营气，用以奉养身形，没有比这更珍贵的了。”前人曾说：鬼疰等三种证候，极大地危害生气，但它们必然潜伏在阴血之中，才肆意作恶。赭石色如丹青，能承宣君火与相火，作为血之统帅进行保任，使气血回归规矩，符合尺寸（指经络气血运行的节律），以契合五十营（指气血在体内循环五十周次的规律），奉养身中生气如同往常，营血安堵如故。

【气味】味咸，性寒，无毒。
【考证】曰：戎盐，就是青盐，也有赤盐。史书记载胡人地区的盐有九种：叫白盐、食盐、黑盐、胡盐、柔盐、赤盐、驳盐、臭盐、马齿盐，其中戎盐就是胡盐。日华子称为羌盐，《唐本草》称为秃登盐，大明称为阴土盐，产于河崖山之背阴处的土石之间。大小不一，形状呈块片状，间或有方棱，有的像鸡蛋，有的像菱角米，坚硬结实似石头，颜色玄紫白相间，味道不是很咸，气味像鸡屎的气味，燃烧时不发出声响的就是它。《凉州异物志》说：“姜赖的废墟，现在称为龙城。方圆千里都是刚卤之地，长满蒺藜。地下有盐，像棋子一样堆积而生。”又说：“盐山有两座山峰，两种颜色为质，红色的像丹砂，黑色的像漆。大小随意，雕刻成各种器物。做成兽形可辟邪，佩戴可求吉利。”有人称戎盐可以疗疾。张果《玉洞要诀》说：“赤戎盐，产于西戎，禀受自然水土之气，凝结而成质。那里的水土之气黄赤，所以盐的颜色越红越真。再经过长时间烧炼，红色会转为青色。所以又名绛盐。”《西凉记》说：“有青盐池，出产青盐，每块正方寸半，形状像石头，味道非常甘美。”《真腊记》说：“山间有石头，味道胜过盐，可以雕琢成器皿。”《梁杰公传》说：“交河之间，挖掘沙地数尺下有紫盐，颜色红紫，色泽鲜艳且甘甜。其下一丈左右，必有琥珀。”《北户录》说：“张掖池中生出桃花盐，颜色像桃花，随月亮盈亏而变化。”如今宁夏靠近凉州的地方，盐井所出的青盐，四方皎洁如石。山丹卫，即张掖地，有池产出红色盐。这两种盐，就是戎盐的青、赤二种盐。如今医方书中只用青盐，不用赤盐，并把赤盐视为异物。《本草》说：“北海产青盐，南海产赤盐，都从西戎传来。”所谓的南北，是指西海的南北而言。岭南有一种红盐，是用颜色染成的，不是真正的赤盐，燃烧后会流出白色汁液，凝固后仍转回白色。《丹房源》说：“蛮盐可以伏雌雄，只有赤盐为上品。”独孤滔说：“戎盐累卵，干燥后可用于制土砂。”
【按语】曰：煮海水为盐，像戎盐这样的，是汇聚海水自然的精气，不假借人力制作。生于海北的，黑如漆；生于海南的，不超越水火之色，依次以水火来区分优劣，也依次以水火来发挥功用。所以主治眼睛明亮有神，是因为眼识的产生缘于水，生于眼识，盖因识精以水为根，缘明为尘，尘为火用，根为火体，所以如此。至于益气、坚筋骨、去毒蛊，这是宝明（火）澄湛（水）的美好征兆啊。

The Shuai (Commander) leads the Wei Qi (Defensive Qi) to protect the exterior. There are twenty-four on the left and right [referring to the distribution of Defensive Qi in the Six Yang Meridians], while the Ying Qi (Nutritive Qi) formation occupies the center. If there were no Commander of Blood, who would preside over life?
[Odor and Flavor] Bitter, cold, non-toxic.
[Indications] Primarily treats Gui Zhu (Ghost Attachment), Zei Feng (Thief Wind), Gu Du (Gu Poison). It kills spirits and evil ghosts, eliminates toxic pathogenic qi in the abdomen, and treats women's red leukorrhea and metrorrhagia.
[Verification] Says: Dai Zhe Shi (Hematitum) is produced in Dai Commandery and Gumu. The Classic of Mountains and Seas (North Mountain Canon) states: "In the mountains of Shaoyang, there is much fine hematite." The West Mountain Canon states: "On the mountain of brittle stone, the Guan River originates; within it flows hematite." The Guanzi states: "Where there is hematite in the mountains, there is iron beneath." Hematite is found in mountains everywhere, but those from the northwest are considered superior. Those growing in mountain gorges are reddish-cyan with a luster, their surface texture resembling floating bubbles, commonly known as Ding Tou Zhe (Nail-Head Hematite). Processing method: Grind finely, then wash repeatedly with water collected in the twelfth lunar month. Remove the reddish impurities floating on the surface like thin clouds. After clarifying and discarding the water, boil in tea decoction for one shi (approx. two hours). Take out, grind more than ten thousand times before use. Alternatively, heat an iron cauldron until red-hot, add one liang of white beeswax. Wait for it to melt, then pour in freshly drawn well water to shock it. Boil again for twenty or so boils, take out, and dry in the sun for use.
Ancestors said: Removing the floating red color deprives it of its initial aggressive nature; cooking with white beeswax cultivates its root. Thus, great protection and support are gained for the Liver and Blood.
[Commentary] Says: The Ling Shu (Spiritual Pivot) refers to Wei Qi as the "Shuai" (Commander). Tao Hongjing refers to Da Zhe Shi (Large Hematite) as the "Blood Master." Therefore, Da Zhe Shi should be regarded as the commander of Ying Qi. The Classic states: "It is named Ying Qi, used to nourish the body; nothing is more precious than this." Ancestors said: The three syndromes of Gui Zhu greatly harm the Sheng Qi (Vital Qi), but they must hide within the Yin Blood to wreak havoc. Hematite, colored like cinnabar and azurite, conveys the Ministerial Fire and Sovereign Fire, acting as the Blood Commander to provide support, allowing Qi and Blood to return to order and measure, harmonizing with the fifty circuits of circulation, thereby sustaining the Vital Qi as usual, and keeping the Nutritive Blood secure and stable.

[Odor and Flavor] Salty, cold, non-toxic.
[Indications] Primarily improves vision, treats eye pain, tonifies Qi, strengthens sinews and bones, and eliminates toxic poisons.
[Verification] Says: Rong Yan (Military Salt) is Qing Yan (Green Salt), which also includes Chi Yan (Red Salt). Historical records state that the salt of the Hu people comes in nine types: Bai Yan (White Salt), Shi Yan (Table Salt), Hei Yan (Black Salt), Hu Yan (Hu Salt), Rou Yan (Soft Salt), Chi Yan (Red Salt), Bo Yan (Mottled Salt), Chou Yan (Stinking Salt), and Ma Chi Yan (Horse-Tooth Salt). Among these, Rong Yan is Hu Yan. Ri Hua Zi calls it Qiang Yan. The Tang Ben Cao calls it Tu Deng Yan. The Da Ming Ben Cao calls it Yin Tu Yan. It grows in the earth and stones on the shady side of Heya Mountain. Its size varies; its shape is blocky or sheet-like, sometimes with square edges, resembling chicken eggs or water caltrop seeds. It is hard and compact like stone, with colors ranging from dark purple to white. Its taste is not very salty, and it has an odor similar to chicken droppings. When burned, it does not crackle; this is the true Rong Yan. The Liangzhou Yiwu Zhi states: "In the ruins of Jianglai, now called Longcheng. For a thousand li, the land is saline and barren, covered with tribulus. Beneath lies salt, accumulating like chess pieces." It further says: "There are two peaks of Salt Mountain, with two colors as substance: red like cinnabar, black like lacquer. Their sizes vary, carved into various objects. Made into beast shapes to ward off evil, worn for good luck." Some say Rong Yan can treat diseases. Zhang Guo's Yudong Yaojue states: "Chi Rong Yan (Red Military Salt) is produced in the Western Regions, formed by condensing the natural qi of soil and water. The local soil and water qi are yellow and red, so the redder the salt, the truer it is. After prolonged burning, the red turns green/blue. Hence, it is also called Jiang Yan (Crimson Salt)." Xiliang Ji states: "There is a Green Salt Pool producing Qing Yan. Each piece is half a square inch, shaped like stone, with a very sweet and delicious taste." Zhenla Ji states: "In the mountains, there are stones that taste better than salt and can be carved into vessels." Liang Jiegong Zhuan states: "Between Jiaohe, digging several feet into the gravel reveals Zi Yan (Purple Salt), red and purple in color, fresh and sweet. About one zhang below, amber is often found." Beihu Lu states: "In Zhangye Pool, Peach Blossom Salt grows, colored like peach blossoms, expanding and contracting with the moon." Today, near Liangzhou in Ningxia, the Qing Yan from salt wells is bright and clean like stone. Shandan Wei, i.e., Zhangye area, has pools producing red salt. These two salts are the Qing and Chi varieties of Rong Yan. Currently, medical formularies only use Qing Yan, not Chi Yan, regarding Chi Yan as an anomaly. The Ben Cao states: "Qing Yan is produced in the North Sea, Chi Yan in the South Sea, both originating from the Western Regions." The terms North and South refer to the north and south of the Western Sea. In Lingnan, there is a type of red salt dyed with color, which is not true Chi Yan; when burned, it exudes white juice, solidifying back to white. Dan Fang Yuan states: "Man Yan (Barbarian Salt) can subdue yin and yang, with Chi Yan being the best." Dugu Tao states: "Rong Yan accumulates like eggs; when dried, it can be used to process Earth Cinnabar."
[Commentary] Says: Boiling seawater to make salt is human labor. However, Rong Yan gathers the natural essence of seawater without artificial intervention. Produced north of the sea, it is black as lacquer; produced south of the sea, its color does not exceed the hues of water and fire. Water and fire determine its superiority or inferiority, and also its therapeutic functions. Thus, it primarily benefits clear vision and insight because eye consciousness arises from water. Essence of consciousness roots in water, clarity serves as dust, dust utilizes fire, and the root is the body of fire. As for tonifying Qi, strengthening sinews and bones, and eliminating toxins, these are auspicious signs of Bao Ming (Fire) being clear and Cheng Zhan (Water) being tranquil.
(Bao Ming refers to Fire, Cheng Zhan refers to Water. The Classic states: Bao Ming generates moisture, and water emerges from fire.)
